role_routine_grants
   The view role_routine_grants identifies all
   privileges granted on functions where the grantor or grantee is a
   currently enabled role.  Further information can be found under
   routine_privileges.  The only effective
   difference between this view
   and routine_privileges is that this view omits
   functions that have been made accessible to the current user by way
   of a grant to PUBLIC.
